    Can anyone tell me definitively if a 1920x1080 DVI display will work with an Aluminum PowerBook 15" 1.5GHz?

    When I look at the Apple specs page, it says that it can handle external monitors up to 2048 x 1536 on the external display, but that does not specifically state that it supports this resolution. This one is special because it is 16:9, which is not particularly standard for monitors.

    The card in this model is an ATI Radeon 970. However, their website is completely unhelpful. The paheon the 970 makes no mention whatsoever of Macs, but does go out of its way to note that 1920x1080 is only supported on some OSes.

    So has anyone successfully run a 1920 x 1080 monitor on a PowerBook? Any real-world input or a link to a definitive answer would be greatly appreciated!

    P.S. I'm looking at the ASUS VH242H display.

    I'm fairly certain that it could.

    SwitchResX can force specific resolutions if it isn't listed, but DVI should automatically detect resolutions offered by the monitor.

    I may have found evidence to the contrary. The Apple Developer note on the 15" PB does not list that resolution.

    Anyone know what would happen if I plug this monitor into a 15" Aluminum PB?

    Or more to the point... can anyone recommend a nice ~21" DVI monitor that is great for graphics work, works with a PB, and costs <$200? :)

    It says up to that resolution, which means that the graphics card is capable of pushing that many pixels through the pipe. 1920x1080 might not show up in the list, which is why you'd need the program geoffreak keeps recommending.

    I appreciate the link. However, the site doesn't mention anything about the effect on the display speed. If it is interpolating through software, I can imagine that it could make a big hit. Or perhaps not.

    Do you use it and can you comment on speed?

    It works

    FYI, the answer is yes, it does work and it does not need additional software.

    Just got an ASUS VH242H 1920 x 1080 display and plugged it in to a 1.5GHz 15" PowerBook via DVI and it worked instantly (in Leopard).
